As Creative Director of Bottega Veneta, Mr Tomas Maier aims to keep the house's values of craftsmanship and timeless design at the forefront. These classic D-frame sunglasses are just one of the results. They've been made in Japan from tortoiseshell acetate and reinforced with a gunmetal-tone bridge and arms - the engraved pattern takes its cue from the intrecciato technique used to weave the brand's artisanal leather goods.
